The net ionic equations for the given “molecular” reactions using solubility rules are to be stated. The processes that give a clear visual evidence of an ion exchange process are to be identified. Concept introduction: When an amount of solute completely dissolves in a solvent, then it is called soluble, and when it is does not completely dissolve it is termed insoluble. Ionic compounds dissociate into their individual ions in aqueous solution. Some examples of ionic compounds are sodium chloride, potassium nitrate and potassium chloride. Some solubility rules for ionic compounds are, The alkali metal salts are soluble. Examples are Sodium chloride, potassium chloride. The salts in which nitrates are present are soluble. Ammonium salts are soluble. Sulfides, carbonates and phosphates are insoluble but sulfides, carbonates and phosphates of the alkali metal and ammonium sulfides, carbonates and phosphates are soluble. To determine: The balanced net ionic equations for the given “molecular” reactions.

Show that a molecule with configuration π4 has a cylindrically symmetric electron distribution. Hint: Let the π orbitals be equal to xf and yf, where f is a function that depends only on the distance from the internuclear axis.

(a) Verify that the lattice energies of the alkali metal iodides are inversely proportional to the distances between the ions in MI (M = alkali metal) by plotting the lattice energies given below against the internuclear distances dMI. Is the correlation good? Would a better fit be obtained by plotting the lattice energies as a function of (1 — d*/d)/d, as theoretically suggested, with d* = 34.5 pm? You must use a standard graphing program to plot the graph. It generates an equation for the line and calculates a correlation coefficient. (b) From the graph obtained in (a), estimate the lattice energy of silver iodide. (c) Compare the results of (b) with the experimental value of 886 kJ/mol. If they do not agree, explain the deviation.
